FIELD: technological processes.
SUBSTANCE: invention concerns container for printing material, particularly to device preventing accidental tangency of contacts positioned on it. Container for printing material is connected to printing device by insertion of an insert in specified direction and includes case with printing material; contact set of low-voltage circuit touching contact set of low-voltage circuit of printing device in the first position when container for printing material is connected to printing device; contact set of high-voltage circuit touching contact set of high-voltage circuit of printing device in the second position when container for printing material is connected to printing device. The second position is shifted in insertion direction farther than the first position. In one of implementation versions contact set of high-voltage circuit includes one earthing contact positioned in the first row and farther to the insertion direction side than contact set of low-voltage circuit, while another contact of contact set of high-voltage circuit beside earthing contact is positioned so as to form second row parallel to insertion direction and differing from first row. One earthing element is connected to the contact forming second row over a capacitor. Also invention claims printing device with a holder of container for printing material, featuring contacts.
EFFECT: prevention of short-circuit between container contacts with differing voltage in a container with at least two contact types.
